| Nowadays, the organic farming sector is growing at a fast pace in Europe while needs to face the lack of organic protein sources and in particular, feeding monogastric animals is becoming more and more urgent. Green biorefinery concepts might become the suitable solution for the sustainable production of organic protein-rich feeds from green crops. In this context, red clover, clover grass, alfalfa and oilseed radish were studied as possible feedstocks for the development of an organic biorefinery system in Northern Europe. For this purpose, the green crops were processed into a nitrogen-rich protein concentrate, a fiber-rich press cake, and a residual stream of soluble nutrients (brown juice). The process, which involved a novel protein refining technique... |

| Lactic acid bacteria (LAB) have extensive industrial applications as producers of lactic acid, as probiotics, as biocontrol agents and as biopreservatives. LAB play a large role in food fermentation and in silage processes, where crops such as grass, legumes, cereals or corn are fermented into high-moisture feed that is storable and can be used to feed cattle, sheep or other ruminants. LAB also have great applications within green biorefineries, with simultaneous production of protein-rich feed for monogastric animals, silage or feed pellets for ruminants and production of lactic acid or specific amino acids. In green biorefineries, fresh or ensiled wet biomass is mechanically fractionated into green juice and solid residues (press cake), where the plant... |

| Nowadays, the organic farming sector is rapidly increasing in order to meet the increasing demand for organic products. However, the scarce availability of organic feed for monogastric animals together with the lack of organic fertilizers are challenging the development of this sector. In this context, a Danish project called Organofinery is focusing on developing a green biorefinery platform for the production of organic protein-rich feed for monogastric animals, of biogas and of organic fertilizer. In the Organofinery concept, the freshly harvested green biomass is separated by a screw press into a green juice and a press cake. Soluble sugars contained in the green juice are fermented by specific lactic acid bacteria, leading to a drop of the pH and... |

| Nutrient recovery from organic green biomass after processing in a green biorefinery concept for the production of protein feed, biogas and fertilizer for organic farming was investigated. Mass balances in terms of wet weight, TS, VS, C, N, P, K and S were evaluated for processing red clover and clover grass into protein concentrate, press cake and brown juice according to the green biorefinery concept. The analysis was based on mass flows and composition of each of the fractions produced. Depending on the biomass, between 60-79% of C and between 52-63% of N, P and S in the fresh biomass were found in the press cake, while only 6-10% of C, 8-15% of N, but up to 27% of P and up to 26% of S were found in the brown juice. In contrast, less than 45% of K was... |

| The supply of organic protein feed for monogastric animals (i.e. poultry and pigs) with the right amino acid profile and a competitive price is one of the major challenges for organic agriculture nowadays. In this project, the development of an organic protein concentrate able to substitute the soybean protein while competing with the current market prices is assessed. The product is developed from red clover biomass, using a sustainable technology without the use of inorganic acids or organic solvents. It also contains some lactic acid, which is supposed to be beneficial for the monogastric livestock. The quality of this protein concentrate is evaluated in terms of amino acid composition. The suitability of the obtained product as feedstock for poultry... |

| The aim of this report is to summarize our present knowledge on the bio-technical as well as economic issues in relation to value creation of green biomass in Denmark. This includes many types of knowledge from the different types of actors included in activities going on at present in this field. To start the work, a kick-off workshop was held in Copenhagen in January 2016, where a range of stakeholders from many fields enthusiastically expressed their views and ideas as regards what to include and take into account in the report. We have tried to include these as far as possible. Thus a number of persons have contributed directly in the writing process whereas as others have contributed with particular overall insight. |
